*deep inhale* I LOVE the smell of jet-a in the morning..

In response to Barbers Pole’s comment that oxygen mask have to be worn continuously in his company at FL410 and above, and earnest’s comment that the Crew mask’s have a better fit than the drop down masks for the pax. Can anyone tell me what the rapid descent procedure is for Concord at mach 2, has this ever been carried out with pax on board on a revenue flight ? And are the paz masks in Concord more robust to cope with the lower pressure ?

manuel ortiz:

High altitude can cause pulmonary oedema. This is a reaction to the low partial pressure of oxygen in which some people get 'leaky' capillaries in their lungs. This produces shortness of breath and can be severe enough to be life threatening. Classically pulmonary oedema is worsened by lying flat and improved somewhat by sitting upright.

Perhaps you had a mild dose thereof.
